A 60kHz signal is transmitted from Anthorn in Cumbria, encoding the exact time. I use the EM2S 60 kHz receiver module available from HKW to decode this signal, interfaced with a PIC16F727. This board is for the Embedded Systems course, a module in Computer Science at Lancaster University. This allows the students to demonstrate their assembly coding skills by decoding the timing signal and display it on the LCD panel. Lucky, lucky students. The link to the course work based on this board is here. Why the PIC16F727? Well, I'd just completed some touch sensor boards using Microchip's mTouch technology. Modifying an existing board seemed the least painful route to go.
Complete courseboard. Thanks to Jessica Froude for taking the photo.
